A Night to Remember

To start this sidequest, find Sam Guenvenne in a random inn at any hold or town, and accept his challenge to a drinking contest. After a few cups, your screen will black out and you'll wake up in the Temple of Dibella, in Markarth. Talk to the priestess named Senna to start the quest.

Pick up the two alto wine bottles scattered on the floor to clean up the temple. Next, go to Rorikstead and talk to a guy named Ennis. He will immediately confront you about his prized goat, Gleda that you apparently sold to the giant.

If your Speechskill is high, you'll have the option to bribe, persuade or intimidate him to give you the details about Sam's last location. Otherwise, you'll have to rescue his goat from the giant.

Just follow the marker and you'll eventually find Grok the giant and the goat. Kill it and talk to the goat for it to follow you. Lead it back to Ennis to update your objectives.

Travel to Whiterun and follow the quest marker to find Ysolda. You'll have to find the wedding ring in Witchmist Grove. Like Ennis, you can bypass this task by bribing, persuading or intimidating as long as your Speech level is high enough.

If you don't have the choice but do it the hard way, head to Witchmist Grove and approve the hagraven named Moira. Kill the disgusting hag and take the wedding ring from her. You can also read the book under her bed entitled "Response to Bero's Speech" to increase your Destructionskill. Return back to Whiterun and deliver the ring to Ysolda.

Next,you have to travel to Morvunskar. As soon as you arrive, you have to fight a few conjurers outside. After clearing the yard, enter the fort. Fight your way to the basement and kill the storm wizard. Once done, climb the stairs and approach the marker. A portal will appear so enter it and you'll be taken to the Misty Grove. Follow the path until you find Sam. Talk to him as he reveals himself as Sanguine and he'll give you the staff and lead you out of the place. Quest complete.
